The Norse-Gaelic Clan Donald traces its descent frae Dòmhnall Mac Raghnuill (d. circa 1250), whose faither Reginald or Ranald wis styled "Keeng o the Isles" an "Laird o Argyll an Kintyre". Ranald's faither, Somerled wis styled "Keeng o the Hebrides", an wis killed campaignin against Malcolm IV o Scotland at the Battle o Renfrew in 1164. Clan Donald shares a descent frae Somerled wi Clan MacDougall, who trace their lineage frae his elder son, Dugall mac Somhairle. Their dynasties are thegither commonly referred tae as the Clann Somhairle. Furthermair they are descendit maternally frae baith the infamous House o Ivar an the Earls o Orkney, through Somerled's wife Ragnhildis Ólafsdóttir, dochter o Olaf I Godredsson, Keeng o Mann an the Isles an Ingeborg Haakonsdottir dochter o Haakon Paulsson, Earl o Orkney. It is possible that Somerled wis a male line descendant o Echmarcach mac Ragnaill an Ivar o Waterford.
Gaelic tradition gave Somerled a Celtic descent in the male line, as the medieval Seanachies traced his lineage through a lang line o ancestors back tae Colla Uais an Conn o the Hunder Battles. Thus Clan Donald claimed tae be baith Clann Cholla an Siol Chuinn (Childer o Colla an Seed o Conn). Possibly the auldest piece o poetry attributit tae the MacDonalds is a brosnachadh (an incitement tae battle) which wis said tae hae been written in 1411, on the day o the Battle o Harlaw. The first lines o the poem begin "A Chlanna Cuinn cuimhnichibh / Cruas an àm na h-iorghaile," (Ye children of Conn remember hardihood in the time of battle). A later poem made tae John o Islay (1434–1503), last o the MacDonald Lords o the Isles, proclaims "Ceannas Ghàidheal do Chlainn Cholla, còir fhògradh," (The Heidship o the Gael tae the family o Colla, it is richt tae proclaim it), givin MacDonald's genealogy back tae Colla Uais.
Housomeivver a recent DNA study haes shown that Somerled mey hae been o Norse descent in his male line. Bi testin the Y-DNA o males bearin the surnames MacDonald, MacDougall, MacAlister, an their variants it wis foond that a substantial proportion o men testit shared the same Y-DNA an a direct paternal ancestor. This distinct Y-chromosome R1a1 haplotype foond in Scotland haes been regardit as aften showin Norse descent in the Breetish Isles. Accordin tae the Clan Donald USA DNA Project aboot 22% o testit participants hae this signature, but despite the sensational claims it remains far frae proven that Somerled hissel wis o paternal Norse ancestry. A non-paternity event remains a possible cause.
Scots-Norse War 
The MacDonalds haed aaways supportit Norawa. Housomeivver, this alliance brak when the Norsemen wur defeatit at the Battle o Lairgs in 1263 bi Scots forces. Norawa's Keeng Haakon wis defeatit an his fleet wis wrecked bi the skilled manoeuvres o Keeng Alexander III o Scotland and the Clan MacDougall.
